GAS-HEATER.

Specification of Letters Patent.

Application filed November 30, 1910.

Patented Apr. 25, 1911.

Serial No. 594,821.

To all whom it may concern:

Be it known that I, OHAnLns HOHMANN, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Gas-Heaters; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to figures of reference marked thereon, whichform a part of this specification.

This invention consists of a heater which comprises a radiator whichreceives and distributes the heat from a burner, the radiator resting ona supporting structure which is usually made from wires so as to permitthe light from the burner to issue, the support ing structure beingadapted to be secured to or removed from a burner, such as a gas burneror a lamp burner.

The invention further consists of inclosing plates which are suspendedfrom the radiator and which can be assembled and fastened together atthe bottom to inclose the light from the heater so that it can be usedentirely for heating purposes, or which can be swung upward andmaintained in their upward positions so that there is no interferencewith the light from the burner and it is free to be used for lightingpurposes.

The invention further consists of means for opening the radiator toregulate the heat that issues therefrom. The radiator has a bottom platewhich is directly above the burner, or the chimney of the burner andreceives the heat directly therefrom, which is provided with wiresstrung across the bottom to receive the heat and which are adapted toget red hot and to quickly transmit their heat to the heater plate andthus facilitate the heating of the radiator.

The invention is illustrated in the accompanying drawing, in which-Figure 1 is a view half in section and half in elevation showing theheater mounted on a burner, the burner being shown in dotted outline.Fig. 2 is a bottom view of the bottom plate partly broken away, and Fig.3 is a perspective of a part of the heater of a modified form.

The heater is adapted to be mounted on any suitable burner 10, which canbe a gas burner or an oil burner, which is provided with a chimney 11. Aband 12 is split and provided with a fastening means, such as a lip 13,between its abutting ends whereby it can be clamped around a burner. Theband thus forms a clamp which can be fastened around the burner, theclamp having wires 14: projecting up therefrom, which wires form asupport for the radiator which it holds above the burner and in such away that it is a short distance above the chimney and receives the heatfrom the flame that comes up through the chimney.

The radiator consists of a double heater plate, called the bottom heaterplate 15, which is provided with perforations 16in the top and bottom ofthe double plate, the double plate having a space between the top andbottom, which space is perforated around the side edges or on itsperiphery with the openings 17. The upper double heater plate 18, withthe perforations 19 in its top and bottom surface, is supported abovethe double bottom plate and is spaced therefrom by a radiator plate 20provided with perforations 21, all these plates being adapted to beheated by the heat from the chimney and to radiate the heat through theperforations and through the perforations 22 of the inclosing plate 23which is connected with the peripheries of the top and bottom doubleheater plates and has a top 23 thereon. The inclosing plate ispreferably upwardly and inwardly inclined to form a heater section ofthe shape of a truncated cone.

Pivotally suspended from the outer edge of the bottom of the radiatorare the inclosing plates 24 which can be provided with the perforations25. These inclosing plates for the bottom can be arranged to swing, andthe preferred way is to have them suspended on the wires 26, which wiresproject from the double bottom heater plate and have another functionwhich will be hereinafter described. The inclosing plates 24 can beassembled so that they form a chamber around the chimney, beingpreferably held by being snapped behind the bead 27 of the band 12,which bead can have a spring action and can be split at intervals so asto hold the inclosing plates against any accidental movement, butpermits their being pulled from place by a tug when it is desired toopen the bottom part of the heater..

\Vhen the heater is to be used at its maximum these inclosing plates areswung shut and snapped into place, and then the heater becomesthoroughly heated and radiates the heat so as to give off considerableheat and quickly warm the room and keep it at a high temperature.

If the burner is to be used for lighting purposes as well as heating,the inclosing plates 24 are removed from their engage,

ment with the bead 27 and are swung upward to the position shown indotted outline to the left of Fig. 1 where one of the inclosing platesis shown supported against the radiator, the inclined surface of theoutside of the radiator forming means for holding the inclosing platesin place. When the inclosing plates are raised to this position shown indotted outline in Fig. 1 there is no interference with the light fromthe heater, and it is well adapted for lighting purposes. The wires 26can be secured to the heater plate 15 in any desired way, but I preferto extend them across the lower face or surface as shown in Fig. 2,these wires receiving the heat directly from the chimney of the burnerand they soon become red hot, they assist the bottom plate in becomingred hot, and they facilitate the heating of the device and also serve toretain considerable heat and then quickly transmit the heat to thedifferent parts of the heater and particularly to the double bottomplate.

A modified form of device is shown in Fig. 3 where the radiator has thetop 28 supported on the bottom plate 15 by wires 29 which are spacedapart, each one acting as a support for the hinges 30 of a wing 31,these, wings, when all are shut, acting to inclose the radiator andhaving the openings 32 to permit the heat to issue from the radiator.These wings are normally held shut by latches 33 fitting over studs 84:,although other means of locking the wings shut can be devised. When moreheat is desired one or more of the wings can be opened, as shown in Fig.3, and in this way the heat that issues from the radiator can beregulated according to the requirements. Perforations 35 can be made topermit heat to pass out between the top and bottom of the upper doubleheater plate, as will be evident from an inspection of Fig. 1.

The heater is compact and efficient and combines a heater that can beused entirely for heating, and one that can also be used for heatingwithout interfering with the use of the burner for lighting purposes.

Having thus described my invention, what I claim is 1. The combinationof a burner, with a heater comprising a radiator, means for supportingthe radiator on the burner, and inclosing plates depending from theradiator and adapted to inclose the burner and being adapted to be swungupward against the radiator to permit the use of the burner for lightingpurposes.

2. The combination of a burner, with a heater comprising a radiator, awire support, a clamp on the bottom of the wire support for detachablysecuring the device to the burner, and inclosing plates depending fromthe radiator and adapted to be secured to the clamp and arranged to beswung against the radiator to permitthe burner to be used for lightingpurposes.

3. The combination of a burner, with a heater comprising a radiatorhaving an upwardly and inwardly inclined outer surface and adapted toreceive and radiate heat from the burner, a support for detachablysecuring the radiator above a burner, and

inclosing plates arranged to swing on the V edges of the radiator andadapted to be detachably secured to the support and being also adaptedto be swung upward and lie against the inclined surface of the radiatorso that the burner can be used for lighting 5. The combination of aburner, with a heater comprising a radiator formed of an inclosing platehaving perforations therein, a lower double heater plate at the bottomof the inclosing plate, an upper double heater plate having perforationstherein, the lower heater plate also being perforated, a support fordetachably securing the radiator above the burner, and inclosing platesswinging on the periphery of the radiator, the inclosing plates beingadapted to be secured in their lowered position and also being adaptedto be swung upward and held in their raised positions whereby the burnercan be used for lighting purposes.

6. The combination of a burner, with a heater comprising a radiator withan inclosing plate having perforations therein, a lower double heaterplate, an upper double heater. plate, the heater plates beingperforated, a tubular radiating plate extending from one double heaterplate to the other and spacing them apart, a support secured to theradiator, a clamp at the bottom of the support for detachably securingit to the burner, and inclosing plates swinging on the edge of theradiator, the inclosing plates and the clamp having co-acting means fordetachably holding them together, the inclosing plates being adapted tobe swung up against the radiator to permit the burner being used forlighting purposes.

7 The combination of a burner, with a heater comprising a radiatorconsisting of a lower double heater plate, an upper double heater plate,the upper plate being smaller in diameter than the lower, an upwardlyinclined inclosing plate having perforations therein, wires supportingthe radiator, a clamp secured to the bottom of the wires for detachablysecuring the device to theiburner, and inclosing plates arranged inswinging relation to the periphery of the radiator,

said inclosing plates being adapted to be held together in their loweredposition to inclose the burner and also being adapted to be swung upwardand lie against the inclined inclosing plate and permit the use of theburner for lighting purposes.

In testimony, that I claim the foregoing, I have hereunto set my handthis 28th day of November 1910.
